It's safe to get back on the playground. That was the primary conclusion of a European study indicating that regular physical exertion does not appear to put kids with type 1 diabetes at risk of experiencing dangerously low blood sugar. The study, conducted jointly by German and Austrian researchers, was published in the Archives of Pediatrics & Adolescent Medicine. Researchers monitored more than 19,000 type 1 diabetics ranging from toddlers to adolescents. According to their results, those kids who were the most physically active did not suffer from significantly more episodes of low blood sugar than those who were less active. In addition, researchers noted the benefits that can result from regular exercise for diabetics, including lower risk of obesity, lower blood pressure and healthier cholesterol levels.
